David Valner has a background in glass design, sculpture, fine arts, and interactive media. David has grown up in a glassmaker family, in the midst of a swarm of traditional artisans–glass lovers, feeling and watching  the physical and metaphorical fire of creation. At the centre of his current approach to glass stands respect for the material as an originally free and fluid mass. Endlessly inspired by nature, he creates collections of objects in which each item is an original and defects are embraced as deeply meaningful and inspirational testimonies to artisan glass making as opposed to mass production.
